Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
Investor B1 Shares	$	587	$	879	$	1,195	$	1,999
Investor C1 Shares	$	292	$	594	$	1,021	$	2,212

You would pay the following expenses if you did not redeem your shares:

	1 Year		3 Years		5 Years		10 Years
Investor B1 Shares	$	187	$	579	$	995	$	1,999
Investor C1 Shares	$	192	$	594	$	1,021	$	2,212

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund seeks to achieve its investment objective by investing in a diversified portfolio of securities that are issued by utilities companies including telecommunications companies. Under normal circumstances, the Fund will invest at least 80% of its assets in equity and debt securities issued by domestic and foreign utilities and telecommunications companies. Utilities and telecommunications companies include companies that are primarily engaged in the ownership or operation of facilities used to generate, transmit or distribute electricity, telecommunications, gas or water. Equity securities include common stock, preferred stock, securities convertible into common stock or securities or other instruments whose price is linked to the value of common stock. The Fund intends to invest primarily in equity securities, but Fund management may change its allocation among these types of investments as it deems appropriate to seek to achieve the Fund’s objective. The fixed-income securities in which the Fund invests generally are limited to those rated investment grade, and may be of any maturity. Investment grade securities are securities rated in the four highest rating categories by recognized rating agencies including Moody’s Investor Services, Inc., Standard & Poor’s and Fitch Ratings. The foreign securities in which the Fund invests may be issued by companies located in both developed and emerging markets. The Fund may invest in all market capitalization ranges, although the Fund will focus on mid-cap securities. The fund may invest in sovereign debt securities.

Principal Risks of Investing in the Fund

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of certain risks of investing in the Fund.

n Credit Risk — Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer.

n Emerging Markets Risk — Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets.

n Equity Securities Risk — Stock markets are volatile. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions.

n Foreign Securities Risk — Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include:

n The Fund generally holds its foreign securities and cash in foreign banks and securities depositories, which may be recently organized or new to the foreign custody business and may be subject to only limited or no regulatory oversight.

n Changes in foreign currency exchange rates can affect the value of the Fund’s portfolio.

n The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position.

n The governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries.

n Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as does the United States and may not have laws to protect investors that are comparable to U.S. securities laws.

n Settlement and clearance procedures in certain foreign markets may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments.

n Interest Rate Risk — Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall, and decrease as interest rates rise.

3

n Market Risk and Selection Risk — Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by Fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.

n Mid Cap Securities Risk — The securities of mid cap companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies.

n Prepayment and Extension Risk — When interest rates fall, an issuer may redeem a security with call features by repaying it early, and the Fund may have to invest the proceeds in securities with lower yields. When interest rates rise, certain obligations will be paid off by the issuer more slowly than anticipated, causing the value of these securities to fall.

n Sector Risk — Sector risk is the risk that the Fund’s concentration in the securities of companies in a specific market sector or industry will cause the Fund to be more exposed to the price movements of companies in and developments affecting that sector than a more broadly diversified fund. Because the Fund invests primarily in one sector, there is the risk that the Fund will perform poorly during a downturn in that sector.

n Sovereign Debt Risk — Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

n Telecommunications Risk — The telecommunications industry is subject to governmental regulation and a greater price volatility than the overall market and the products and services of telecommunications companies may be subject to rapid obsolescence resulting from changing consumer tastes, intense competition, and strong market reactions to technological developments throughout the industry. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology.

n Utility Industry Risk — When interest rates go up, the value of securities issued by utilities companies historically has gone down. In most countries and localities, the utilities industry is regulated by governmental entities, which can increase costs and delays for new projects and make it difficult to pass increased costs on to consumers. In certain areas, deregulation of utilities has resulted in increased competition and reduced profitability for certain companies, and increased the risk that a particular company will become bankrupt or fail completely. Reduced profitability, as well as new uses for or additional need of funds (such as for expansion, operations or stock buybacks), could result in reduced dividend payout rates for utilities companies. In addition, utilities companies face the risk of increases in the cost and reduced availability of fuel (such as oil, coal, natural gas or nuclear energy) and potentially high interest costs for borrowing to finance new projects.
